What is the solution for 2.5x-5=5?

Answers

Answer 1

Answer:

Simplifying

2.5x + -5 = 5

Reorder the terms:

-5 + 2.5x = 5

Solving

-5 + 2.5x = 5

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 2.5x = 5 + 5

Combine like terms: -5 + 5 = 0

0 + 2.5x = 5 + 5

2.5x = 5 + 5

Combine like terms: 5 + 5 = 10

2.5x = 10

Divide each side by '2.5'.

x = 4

Simplifying

x = 4

Step-by-step explanation:

Answer 2

Answer:

x=4

Step-by-step explanation:

2.5x-5=5

Given a normal distribution with a mean of 28 and a standard deviation of 2.5, what percentage of the data should be between 25.5 and 30.5?

Answers

Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

28 - 2.5 = 25.5.28 + 2.5 = 30.5.

Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.

how to solve (3p⁴ + 2q⁴)²​

Answers

Answer:

9p⁸ + 12p⁴q⁴ + 4q⁸

Step-by-step explanation:

(3p⁴ + 2q⁴)²​ ⇒ The square of (3p⁴ + 2q⁴)

Squares are such bases that multiply itself two times.

⇒ (3p⁴ + 2q⁴)(3p⁴ + 2q⁴)

Simplifying the expression using (a + b)(a + b) = (a x a) + (ab) + (ab) + (b²)

⇒ (9p⁸ + 6p⁴q⁴ + 6p⁴q⁴ + 4q⁸)

⇒ (9p⁸ + 12p⁴q⁴ + 4q⁸) = 9p⁸ + 12p⁴q⁴ + 4q⁸

We know the identity

(a+b)²=a²+b²+2ab

A brand new vehicle costs $25,399. It decreases in value by 8.5% each year after its purchase.

Which function models the value of the vehicle in dollars x years after its purchase?


f(x)=1.085(25,399)x

f(x)=0.915(25,399)x

f(x)=25,399(0.915)x

f(x)=25,399(1.085)x

Answers

The cost after x years is the initial cost minus the amount of decrease after the duration of x years

Percentage Decrease

Given Data

Initial Cost of vehicle = $25,399Rate of decrease = 8.5%Duration = yearly

Let us find 8.5% of $25,399

= 8.5/100*$25,399

= 0.085*25399

= 2158.915

Cost after x years will be

The image shows lines AB and CD.
Are the 2 lines parallel? Explain or show your reasoning.

Answers

Answer:

No

Step-by-step explanation:

To classify the lines as "parallel", the distance between both x-intercepts must be equivalent to the distance between both y-intercepts. In this case, the lines are not parallel because the distance between both y-intercepts is different than the distance of both x-intercepts.

Distance between two y-intercepts: 4 unitsDistance between two x-intercepts: 5 units

Since 4 ≠ 5, the lines are not parallel.

Answer:

No, the lines are not parallel.

Step-by-step explanation:

Parallel lines have the same slope.

Therefore, find the slopes of both lines and compare.  

Slope formula

[tex]\sf slope=\dfrac{change\:in\:y}{change\:in\:x}[/tex]

Line AB

A = (0, 6)

B = (8, 0)

[tex]\implies \sf slope=\dfrac{0-6}{8-0}=-\dfrac34[/tex]

Line CD

C = (-3, 4)

D = (0, 2)

[tex]\implies \sf slope=\dfrac{2-4}{0-(-3)}=-\dfrac23[/tex]

As the slopes of the 2 lines are different, the lines are not parallel.

Answer: 126 mm^2.

Step-by-step explanation: When finding the area of a trapezoid, you need to add two bases, multiply the height, and divide it all in half.  The steps are done below:

First, we need to find the bases and the height.  The bases are are circled below, but it's basically the top and bottom lengths of the triangle.  Base 1 doesn't have to be 10 either, it can be 18 base 2 can be 10, whichever works for you.  All you need is to assign each base with a top or bottom length.  The height is how tall the trapezoid is, which is also circled below.Secondly, we need to add the bases and multiply the height. B1 is base 1, b2 is base 2, and h is the height.  It should look like this: 10 (b1) + 18(b2) = 28, then 28 x 9(h) = 252.Lastly, we need to divide 252 in half, which you can do in two ways.  You can either simply divide 252 by 2, or multiply 252 by 1/2, which both give you the answer 126 mm^2, which is your answer.

The volume of this right trapezoidal prism is 341.25 ft³.

What is the height, x, of the prism?

Enter your answer as a decimal in the box.

Answers

Answer:10.5

Step-by-step explanation: I hope this helps

The height, x, of the right trapezoidal prism is 10.5 ft.

Given that, the volume of this right trapezoidal prism is 341.25 ft³.

We need to find the height x, of the prism.

What is the formula to find the volume of this right trapezoidal prism?

The formula to find the volume of this right trapezoidal prism is Volume=BH.

Where B=Area of the Base and H=Height.

Area of the Base(Trapezium)=1/2(a+b)×h

Where a and b are parallel sides of the trapezium and h= height of the trapezium.

Now, the area of the Base=1/2(8+5)×5=32.5 ft²

The volume of the right trapezoidal prism=32.5×x

⇒341.25=32.5×H

⇒x=10.5 ft

Therefore, the height, x, of the right trapezoidal prism is 10.5 ft.

Answer:

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

Rectangle:

To find the area of the rectangle, we need to mutiply the base and the height. 3 units(base) x 2 units(height) = 6 squared units

Triangle:

To find the area of the triangle is very similar to finding the area of the rectangle. We need to multiply the base and the height and divide it by 2.

Base= 2 units(since it is a rectangle, the opposite side is the same length)

Height = 2 units

Next, we plug it in to this formula: 1/2 bh (b = base and h = height)

multiplying by one half is the same as dividing by 2

The area of the triangle is 2 x 2 = 4

4 divided by 2 = 2 squared units

For the final step, we add the areas together. (6+2 = 8) the label is very important (squared units)

PART A: READING COMPREHENSIONRead the passage below and answer the questions that follow.Across Malaysia, our rivers are the main source of tap water. Despite this, Malaysians are still throwing rubbish into the river. River pollution is a threat to safe drinking water in Malaysia. A recent dry spell caused water Selangor's Sungai Langat cannot be utilised for daily use as pollution caused ammoniacal nitrogen levels to rise above permissible levels. There are many ways to reduce the river pollution such as installing grease traps, maintaining septic tanks, and educating the public on the importance of having clean drains in the neighbourhood.Most of the times, polluted rivers cannot be rehabilitated to their original and natural condition. Nevertheless, minimising drain pollution can be a cost-effective way to improve the condition of the rivers. One of the ways is by installing grease traps to capture oil, and these traps must be regularly maintained. Local authorities will have to carry out enforcement to combat illegal discharge of oil and grease into the sewerage system.In addition, all septic tanks need to be maintained properly. According to the Malaysia Water Industry Guide 2013, there are 4,380 communal septic tanks and 1,298,207 individual septic tanks in Peninsular Malaysia and Labuan. In Selangor, more than 33,000 old individual septic tanks discharge partially-treated wastewater into drains. The septic tanks must be cleaned of any waste once every three years in order for the tanks to function effectively. If this is done periodically, the level of ammoniacal nitrogen in the river can be reduced significantly.Lastly, the most important step to reduce river pollution is by educating the public on the importance of having clean drains in the neighbourhood. It will be meaningless to maintain the drains and septic tanks if the amount of pollutants entering drains is not reduced. The local authorities can organise campaigns and activities such as drain clean-ups to educate the public on this issue. All in all, the cleanliness of our rivers should not be ignored. The recent shortage of waterin Selangor and the water treatment plant being shut down show that an abundant resource of water can deplete too if we do not take proper care of our drains and rivers.Installing grease traps, maintaining septic tanks, and educating the public on the importance of having clean drains in the neighbourhood are some of the ways that can be done to reduce river pollution. By minimising drain pollution and cleaning the septic tanks every three years can help minimise level of ammoniacal nitrogen in the river.
